Description

Technical Field

[0001] The present invention relates to the technical field of solar cells, and particularly to a method, device, electronic device, and storage medium for correcting quantum response data of a two-terminal stacked cell. Background Art

[0002] Quantum efficiency (QE) testing is an important method for evaluating the performance of optoelectronic devices, which refers to the ratio of the number of externally collectable carriers generated by an optoelectronic device (such as a solar cell, a photodetector, etc.) under specific conditions to the number of photons incident on the surface of the device, usually expressed as a percentage.

[0003] In QE testing, a monochromatic light is used to irradiate the optoelectronic device, and the wavelength range of these monochromatic lights usually covers the working spectral range of the device. By measuring the photocurrent generated by the device under the irradiation of monochromatic lights with different wavelengths and combining the known incident light power and wavelength information, the external quantum efficiency corresponding to each wavelength can be calculated.

[0004] A two-terminal stacked cell is a solar cell that stacks two sub-cells with different bandgaps in series longitudinally, that is, in the light incident direction, to form an integrated whole and has only two electrodes for outputting electrical energy.

[0005] During the QE testing of a two-terminal stacked cell, due to the characteristics of the cell, it is necessary to test the two sub-cells separately, and an additional bias light needs to be applied to the other non-tested sub-cell during the test. This additional light source may affect the final test result of the cell. This influence can be mainly divided into three parts: light transmission problem, shunt problem, and light emission coupling problem.

[0006] In the existing testing methods, specific correction schemes have been proposed for the shunt and light emission coupling problems, but no correction method for the light transmission problem has been proposed. Summary of the Invention

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein.

[0060] Figure 1 The figure is a flowchart of a method for correcting quantum response data of a two-terminal stacked cell provided by an embodiment of the present invention. This embodiment is applicable to correcting the light transmission problem generated during the quantum response test of a two-terminal stacked cell. This method can be executed by a correction device for quantum response data of a two-terminal stacked cell. The correction device can be implemented in the form of hardware and / or software, and the correction device can be configured in any electronic device with communication functions. Refer to Figure 1 , the method includes:

[0061] S110. Determine whether the quantum response data of the two-terminal stacked cell is abnormal data.

[0062] Specifically, determining whether the quantum response data of a two-terminal tandem cell is abnormal data refers to analyzing the quantum efficiency-related data generated by the tandem cell under illumination of light with different wavelengths to determine whether these data deviate from the normal range or exhibit characteristics that do not meet expectations. A tandem cell is a solar cell composed of multiple sub-cells made of different materials, and its quantum response refers to the optoelectronic conversion ability of the cell to light with different wavelengths. Generally, the quantum efficiency is calculated by measuring the short-circuit current generated by the tandem cell under illumination of monochromatic light with different wavelengths, and then the quantum response data is obtained. These data can reflect the absorption and carrier collection of each sub-cell inside the tandem cell to light with different wavelengths. For example, when testing the sub-cell to be measured, a bias light with the same spectrum but different light intensities is applied to the non-test sub-cells. If the quantum response data of the sub-cell to be measured measured with different light intensities of the bias light is inconsistent and changes, it indicates that the sub-cell to be measured is affected by the bias light during the test, and the data needs to be corrected. Or, by comparing with the standard value or expected value, the normal range of quantum response data determined based on theoretical calculations, previous experimental experience, or industry standards can be obtained. If the measured quantum response data of the two-terminal tandem cell exceeds this range, it indicates that it may be abnormal. For example, the quantum efficiency at a certain wavelength is significantly lower or higher than the typical value of the same type of cell. Or, through data trend analysis, it can be observed whether the trend of the quantum response data changing with the wavelength conforms to the normal law. Under normal circumstances, the quantum response curve will have a specific change trend in different wavelength regions, such as gradually rising in some wavelength ranges, remaining relatively stable or gradually decreasing in other wavelength ranges, etc. If the data trend shows obvious abnormalities, such as sudden jumps, discontinuities, or a large difference from the theoretical curve, it indicates that the measured data may be abnormal. By determining whether there is an abnormality in the quantum response data of the two-terminal tandem cell, it helps to understand the performance status of the cell and find possible problems, such as material defects, imperfect processes, etc., so as to provide a basis for improving the cell design and production process to improve the optoelectronic conversion efficiency and stability of the tandem cell.

[0063] S120. If the quantum response data of the two-terminal tandem cell is abnormal data and at least part of the abnormal data is caused by the light transmission problem, then correct the abnormal data caused by the light transmission problem.

[0064] Specifically, the light transmission problem of the stacked cell may be caused by various factors. For example, the light transmittance of the encapsulation material of the cell is insufficient, there are gaps or impurities between the internal layers affecting light transmission, there are stains or scratches on the surface, etc. These problems may all cause changes in the propagation and absorption of incident light inside the cell, and further cause abnormalities in the quantum response data. By increasing the bias light intensity and observing the changes in the quantum response data of the sub-cell to be measured in the entire test interval and the monochromatic light wavelength intervals of its own and non-test sub-cells' quantum responses, the source of the abnormal data is determined. When there are abnormalities in the quantum response data of the two-terminal stacked cell and the source of the abnormal data includes the light transmission problem, according to the preset formula, the abnormal data caused by the light transmission problem is corrected.

[0065] The technical solution provided by the embodiments of the present invention, by determining whether the quantum response data of the two-terminal stacked cell is abnormal data, when the quantum response data of the two-terminal stacked cell is abnormal data and at least the abnormal data is caused by the light transmission problem, the abnormal data caused by the light transmission problem is corrected, eliminating the influence of the light transmission problem, so that a more accurate quantum efficiency value can be obtained, which is more in line with the actual situation and is beneficial to further device evaluation or process debugging.

[0066] In some other embodiments, optionally, the two-terminal stacked cell includes a first sub-cell and a second sub-cell; S110 specifically includes:

[0067] When testing the quantum response data of the first sub-cell, a bias light with the same spectrum but different light intensities is applied to the second sub-cell. If the measured quantum response data of the first sub-cell shows a deviation and the deviation exceeds the preset deviation, then it is determined that the quantum response data of the first sub-cell is abnormal data.

[0068] Among them, the preset deviation can be set in advance according to the test requirements. In the embodiments of the present invention, a crystalline silicon sub-cell is used as the first sub-cell and a perovskite sub-cell is used as the second sub-cell for illustration.

[0069] Exemplarily, when testing the crystalline silicon sub-cell, a bias light with the same spectrum but different light intensities is applied to the perovskite sub-cell. After applying the bias lights with different light intensities, the quantum response data of the crystalline silicon sub-cell measured under every two intensities of the bias lights is inconsistent, showing a deviation, and this deviation exceeds the preset deviation, such as 1%. It indicates that the crystalline silicon sub-cell is affected by the bias light during the test. Because theoretically, the test result of the crystalline silicon cell is determined by the monochromatic light, and the bias light should have no influence on the crystalline silicon cell. However, in practice, if the bias light intensity is changed and the test result of the crystalline silicon cell changes, it means that there is an error in the test result and needs to be processed to obtain the real result. Therefore, the data needs to be corrected. Among them, the deviation can be calculated based on the average value and the standard deviation; the average value is calculated through the following formula:

[0070] ; wherein, is the average value, and n is the number of test times.

[0071] The standard deviation is calculated by the following formula:

[0072] ; is the standard deviation.

[0073] The deviation is calculated by the following formula according to the average value and the standard deviation:

[0074] ; is the deviation.

[0075] Figure 2 FIG. Figure 2 is a flowchart of another method for correcting the quantum response data of a two-terminal stacked cell provided by an embodiment of the present invention. The embodiment of the present invention further refines the foregoing embodiment on the basis of the above embodiment. Refer to

[0076] S210. Determine the source of the abnormal data.

[0077] Specifically, when increasing the bias light intensity, if the quantum response data of the first sub-cell increases in the entire test wavelength range of the monochromatic light, and the increase value in the monochromatic light wavelength range of the second sub-cell quantum response is equal to the increase value in the monochromatic light wavelength range of the first sub-cell quantum response, it is determined that the abnormal data is caused by a light transmission problem.

[0078] Exemplarily, when increasing the bias light intensity, if the quantum response data of the crystalline silicon sub-cell increases in the entire test range, and the increase value in the perovskite sub-cell response range is equal to the increase value in the crystalline silicon sub-cell response range, it is determined that the abnormal data is caused by a light transmission problem. As Figure 3 shown, Figure 3 is a data anomaly curve graph caused by a light transmission problem. The abscissa is the monochromatic light wavelength, and the ordinate is the quantum efficiency.

[0079] When increasing the bias light intensity, if the increase value of the quantum response data of the first sub-cell increases in the monochromatic light wavelength range of the second sub-cell quantum response, while the increase value in the monochromatic light wavelength range of the first sub-cell quantum response decreases, it is determined that the abnormal data is caused by a non-light transmission problem.

[0080] Among them, the non-light transmission problem includes a shunt problem or a light emission coupling problem.

[0081] Exemplarily, when increasing the bias light intensity, if the increase value of the quantum response data of the crystalline silicon sub-cell within the response range of the perovskite sub-cell increases, while the increase value within the response range of the crystalline silicon sub-cell decreases, it indicates that the abnormal data is caused by a shunt problem or a light coupling problem. The embodiments of the present invention do not correct the abnormal data caused by the shunt problem or the light coupling problem. As Figure 4 shown, Figure 4 is a data anomaly curve graph caused by a non-light transmission problem.

[0082] In some other embodiments, optionally, S120 specifically includes:

[0083] a. Measuring the quantum response data of the first sub-cell at a preset monochromatic light wavelength , and the quantum response data of the first sub-cell includes: , , , and there is the following relationship:

[0084] Formula (1)

[0085] In the formula, is the quantum response data caused by the shunt problem or the light coupling problem, is the quantum response data caused by the light transmission problem, is the quantum response data generated by the monochromatic light, and the subscript n represents the test cases of applying different bias light intensities.

[0086] Among them, the preset monochromatic light wavelength is any wavelength within the response range of the perovskite sub-cell.

[0087] b. Subtracting the quantum response data of the first sub-cell with different bias light intensities applied, then there is:

[0088] Formula (2)

[0089] c. For the light transmission problem, there is the following relationship:

[0090] Formula (3)

[0091] For the shunt problem or the light coupling problem, there is the following relationship:

[0092] Formula (4)

[0093] Among them, is the proportionality factor of the light transmission problem, is the proportionality factor of the shunt problem or the light coupling problem, is the exponential factor, is the corresponding bias light intensity;

[0094] d. Substitute Equation (3) and Equation (4) into Equation (2) to obtain:

[0095] Equation (5)

[0096] e. Perform at least four tests, and calculate the proportionality factor of the light transmission problem , the proportionality factor of the shunt problem or the light emission coupling problem and the value of the exponential factor ;

[0097] f. According to the proportionality factor of the light transmission problem calculate the quantum response data generated by the light transmission problem for any bias light intensity , monochromatic light wavelength There is the following relationship:

[0098] Equation (6);

[0099] g. At the preset monochromatic light wavelength, perform data correction on the measured quantum response data of the first sub-cell using the following formula:

[0100] Equation (7).

[0101] Optionally, the lower limit value of the bias light intensity accounts for at least 80% of the upper limit value of the bias light intensity.

[0102] Specifically, the difference between the different bias light intensities applied in the test should not be too large, and the lowest intensity should account for at least 80% of the highest intensity.

[0103] Optionally, after S110, it further includes:

[0104] If the quantum response data of the two-terminal stacked cell is abnormal data, and the abnormal data is generated by the light transmission problem and the non-light transmission problem, then first correct the abnormal data generated by the light transmission problem, and then correct the abnormal data generated by the non-light transmission problem.

[0105] Specifically, perform multiple tests with changing light intensities. If the change of abnormal data is different between every two tests, it means that the abnormal data is generated by the superposition of the light transmission problem and the non-light transmission problem, and it is necessary to first correct the light transmission problem and then correct the non-light transmission problem according to the conventional method. As Figure 5 , Figure 6 shown, Figure 5 is a data anomaly curve graph generated by the superposition of the light transmission problem and the non-light transmission problem, Figure 6It is a data anomaly curve graph generated by superimposing another light transmission problem and non-light transmission problem.

[0106] Next, a specific embodiment will be used to specifically introduce the correction method for the quantum response data of the two-terminal stacked cell provided in this application.

[0107] 1. Determine whether the quantum response data of the two-terminal stacked cell needs to be corrected.

[0108] When testing the crystalline silicon sub-cell, a bias light with the same spectrum but different light intensities is applied to the perovskite sub-cell. If the measured quantum response data of the crystalline silicon sub-cell changes, it means that the crystalline silicon sub-cell is affected by the bias light during the test, and the data needs to be corrected.

[0109] 2. Determine the source of the abnormal data.

[0110] When increasing the bias light intensity, if the quantum response data of the first sub-cell increases in the entire test wavelength range of the monochromatic light, and the increase value in the monochromatic light wavelength range of the second sub-cell's quantum response is equal to that in the monochromatic light wavelength range of the first sub-cell's quantum response, it means that the abnormal data is generated by the light transmission problem.

[0111] When increasing the bias light intensity, if the increase value of the quantum response data of the first sub-cell in the monochromatic light wavelength range of the second sub-cell's quantum response increases, while the increase value in the monochromatic light wavelength range of the first sub-cell's quantum response decreases, it means that the abnormal data is generated by the shunt problem or the light emission coupling problem. The abnormal data generated by the shunt problem or the light emission coupling problem is not corrected in the embodiments of the present invention.

[0112] Perform multiple tests of changing the light intensity. If the situation of the abnormal data change is different between every two tests, it means that the abnormal data is generated by superimposing the light transmission problem and the non-light transmission problem. It is necessary to first correct the light transmission problem and then correct the non-light transmission problem according to the conventional method.

[0113] 3. Correction method.

[0114] Use a certain specific wavelength within the response range of the perovskite sub-cell, such as 500 nm. Then, the quantum response data of the crystalline silicon sub-cell measured here consists of three parts. is the response data generated by light emission coupling) (in the embodiments of the present invention, the light emission coupling problem is taken as an example for output to participate in the correction process). is the response data generated by the light transmission phenomenon. is the response data generated by the monochromatic light. Among them, the response data generated by the monochromatic light is the target to be measured. The subscript n represents the test cases under different bias light intensities. The following relationship exists for the quantum response data of the crystalline silicon sub-cell:

[0115] Formula (1)

[0116] Perform multiple tests and subtract the results, then we have:

[0117] Formula (2)

[0118] For the light transmission problem, there is a linear proportional relationship between the bias light intensity and the additional photocurrent response, and the proportionality coefficient can be regarded as a constant within a certain range. Here, we require that the bias light intensities used in the tests should not vary too much, and the minimum intensity should be at least 80% of the maximum intensity. Then, the difference in the abnormal spectral response at different bias light intensities can be calculated; for problems such as light emission coupling, there is an exponential relationship between the bias light intensity and the additional photocurrent response, and the proportionality coefficient will not change within a certain range either. Then, the following equation can be obtained, where is the proportionality factor for the light transmission problem, is the proportionality factor for problems such as light emission coupling, is the exponential factor,

[0119] is the corresponding bias light intensity, then there is the following relationship:

[0120] Formula (3)

[0121] Formula (4)

[0122] Substitute Formula (3) and Formula (4) into Formula (2), and we can get:

[0123] Formula (5)

[0124] Perform at least four tests, then three equations can be constructed according to the above formula to calculate , , three unknowns.

[0125] After calculating , the size of the additional quantum response caused by the light transmission problem at a certain bias light intensity can be further calculated, as shown in Formula (6). Since the wavelength and intensity of the bias light do not change during the test of the crystalline silicon solar cell, the abnormal quantum response generated by the light transmission phenomenon at all wavelengths is equal. Only by subtracting this value in the full wavelength range can the influence of the light transmission phenomenon be eliminated, as shown in Formula (7).

[0126] Formula (6)

[0127] Formula (7)

[0128] Regardless of whether the battery is affected by other problems, the influence of the light transmission problem can be eliminated according to the above method.
